Schematic for Laney irt15h

[orcl2]

Hi folks, does anybody have the schematic for irt15h? iI found the irt studio's schematic, but seems to me that it's not correct. Thx.

Ask Laney support@laney.co.uk. I've found them to be most helpful. One of the few good guys left.

Thx, but seems to me that the HT voltages are wrong, look at this video, the plate voltage is about 252VDC, while the schematic shows abou 400VDC.

I suggest you measure it for yourself. That video also states to use the 2000mA range on the meter when it should say 2000mVDC. You can't get 15 watts out of a couple of EL84 with 250V on the plates. The power transformer has taps on the secondary it might be that the amp in the video has been modified to use those to lower the power output. There is no indication of what voltage those taps are so this is just speculation.


Can you post the schematic so we are all on the same page? Thx. Oh duh! it was in one of the links : IRT-Studio.pdf
